Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

Kiehl's Clearly Corrective Dark Spot Solution 24 ingredients
Normally I avoid products with alcohol, but it’s not an issue with this one. It’s well formulated so that it’s balanced out with other more hydrating ingredients. It absorbed nearly immediately and doesn’t dry out the skin. The results aren’t massive. But I just love the apothecary aesthetic and it works about as well as any other dark spot corrector.
Works as said
I have dark skin and lots of PIH. It lightens them. You can see quicker results with new PIH spots. Holygrail in my routine
